[Docker Rootless] dockerd can't find 'config.json'

[Bambusa29]

Hi all,

The rootless mode work fine but i have a this error message in the 'daemon.log' every minute

"No config file found, using default or config from environment variables"

My "config.json" is in my local user repertory : '/home/omdocker/.docker'.
It can read the context : 'docker context ls'
I have done a 'export DOCKER_CONFIG=~/.docker' and restart docker, but the error are stille here.
Any clue ?
Thx
